Motul's 8100 ECO-NERGY 5W-30 in the 5-liter size is a fully synthetic, fuel-economy engine oil for newer gasoline and diesel engines that call for a Ford WSS-M2C913 fill. The manufacturer describes it as a low-friction, low-HTHS formula, and lists ACEA A5/B5 and API SL performance levels. Its published data sheet gives a kinematic viscosity of 10.1 mm²/s at 100°C and an HTHS viscosity of 3.2 mPa.s at 150°C, with a viscosity index of 163.0. That low-HTHS profile is the reason this grade is chosen for fuel-economy-focused Ford applications instead of a generic 5W-30. Compared with a cheaper bulk 5W-30, the case for this oil rests on specification. The manufacturer notes that the Ford 913D specification carries higher soot handling capacity than 913C. Its dispersant package is designed so that soot from combustion does not build black sludge or raise the viscosity over the drain interval. The manufacturer also states that the 913D standard fully covers the earlier 913A, 913B and 913C requirements. Fuel-economy figures vary by test basis, and the manufacturer's sheet cites up to 10% fuel economy during Diesel engine operation when a 913C-spec lubricant is required, so confirm any percentage with the manufacturer before relying on it. Ford-spec fitment should be matched to the approval in your owner's manual before you buy. The manufacturer's listing includes OEM approvals for Ford WSS-M2C913-D, Jaguar STJLR.03.5003, Renault RN0700 and VW VWC 530 36. Shoppers searching for Ford 913C 5W30 full synthetic, Ford WSS-M2C913-D fuel economy oil, Motul 102898 5L, or ACEA A5/B5 5W-30 low HTHS oil will find the core specification details here.
The manufacturer's data sheet lists the 913C approval, and the manufacturer's current listing shows the 913D approval. The manufacturer states that 913D covers the earlier 913A, 913B and 913C requirements. Check the exact specification in your owner's manual before purchase.
The manufacturer states that the 913D specification includes higher soot handling capacity than 913C, which supports longer drain intervals in applicable engines.
Fill capacity is not confirmed in the manufacturer's documentation for this item. Owners on user forums report that quoted capacities are generally for a dry engine, so they run the engine briefly to fill the filter and passages, then recheck and adjust the dipstick level.
An oil change with this 5W-30 is a manageable DIY job, though the access work varies by vehicle. Owners on user forums describing a PowerBoost F-150 list an 8mm socket for an underbody panel, a 15mm socket for the drain plug and skid plate, and a 76mm end-cap filter wrench, along with boards to raise the truck for clearance. Owners on user forums also report that the oil filter is hard to reach on some EcoBoost engines, so plan your access before draining. Confirm drain plug size, filter part number, and fill quantity in your owner's manual.
